MEXICO CITY – Mexico’s army has uncovered a 755-foot (230-meter) tunnel running under the Sonora-Arizona border that was used to smuggle drugs into the United States.

Mexico’s defense secretariat says the tunnel linked a soon-to-be-opened ice and purified water business in San Luis Rio Colorado, Sonora to a business in San Luis, Arizona.

Gen. Raul Guereca said Saturday that the tunnel was 4.25 feet (1.3 meters) high and reached a depth of almost 60 feet (18 meters) below ground. It had electricity, ventilation and small cars to transport the drugs through the tunnel.

Officials did not say which cartel they thought had built the tunnel. As U.S. authorities have tightened land crossings, tunnels have become a popular way for Mexico’s cartels to smuggle drugs and people into the U.S.
